Using "Users" Command Gets My Name 2 Times?
I Was Looking for Some Shell Commands, and I Took a Look in "Users" Command. I Was Hoping to Get Only 1 Name, but I Got 2: Nori@Nori-Hidamari: ~$ Users Nori...
I was looking for some shell commands, and I took a look in "users" command.
I was hoping to get only 1 name, but I got 2:
nori@nori-hidamari:~$ users
nori nori
And when I run the command "who"
nori@nori-hidamari:~$ who
nori :0 2015-04-09 09:31 (:0)
nori pts/0 2015-04-09 09:48 (:0)
Is this behaviour normal? Or it's bad?
Thank you guys for helping me.

This is normal expected behaviour.
You see your user name twice because you are logged in twice.
[simmel]@[mars]$ users
simmel simmel
The second command
who
shows which user is online right now and it looks like you were online at that time with Graphical Display :0 and pts/0 (a terminal window).
[simmel]@[mars]$ who
simmel tty8 2015-03-30 11:15 (:0)
simmel pts/3 2015-04-09 14:16 (:0)
After opening some more terminals it looks like this:
[simmel]@[mars]$ who
simmel tty8 2015-03-30 11:15 (:0)
simmel pts/3 2015-04-09 14:16 (:0)
simmel pts/4 2015-04-09 14:54 (:0)
simmel pts/8 2015-04-09 14:54 (:0)
After opening more windows the count goes up in users:
[simmel]@[mars]$ users
simmel simmel simmel simmel
It is normal. You will have an entry for the graphical desktop you have logged into (labeled with the corresponding DISPLAY - in this case :0), and one each for each terminal you have open (labeled with the pseudo-terminal corresponding to each of them (pts/X)). Since you're running this command in a terminal, you will of course have one entry corresponding to that terminal, hence a minimum of two.
